In the cation of the title organic ion pair compound, C(23)H(20)ClN(2)O(3) (+)·CH(3)O(−), the cyclohexyl ring shows a half-boat conformation and the dihedral angles between two benzene rings and the pyran ring are 83.14 (7) and 73.18 (9)°. In the crystal, centrosymmetrically related cations are lin...

Sumario: | In the cation of the title organic ion pair compound, C(23)H(20)ClN(2)O(3) (+)·CH(3)O(−), the cyclohexyl ring shows a half-boat conformation and the dihedral angles between two benzene rings and the pyran ring are 83.14 (7) and 73.18 (9)°. In the crystal, centrosymmetrically related cations are linked into a dimer by pairs of N—H⋯N hydrogen bonds, generating an R (2) (2)(12) ring motif. The anion interacts with the dimer through an N—H⋯O hydrogen bond. π–π interactions between pyran rings of adjacent dimers, with a centroid–centroid distance of 3.861 (2) Å, are also observed. |
